Thank you for posting this. Like many others, I have been following the XIM4 development and the only thing I don't like is the no-audio option on the PS4.
I have searched through the other forums but didn't see a clear answer on this. I do not and have not used a gaming headset for my in-game audio. All I have ever used is a BT headset (on PS3) and the default mic/chat cable that plugs into the DS4 on PS4. Gaming with a headset and blocking out all other sound is usually not an option for me, and I wouldn't want to in most cases as I have a 7.1 surround setup that works great.
So, noting this, all I really want is a simple means to chat. Can I simply use the Syba USB adapter and get a mic/headphone unit and have things work this way? Again, all I'm looking for here is chat capability, I don't care about mixing/amp/cleanup etc. As long as folks can hear me (and me them) then I'm good. I'm assuming I'd need a headset that has a dedicated mic/headphone port but I'd imagine I can find a cheap one rather easily.
Would this work in my scenario?
